hello everyone,

I have a 3 spd auto in my 2000 sunfire and i am planning on turbocharging my car. I have 2.84 gears as of now and i am looking to change the gear ratio to better suit my needs. I dont know if i should raise the gear ratio to 3.08 or 3.33 or just stay at 2.84? if any one can help me out it would be greatly appreciated.

Thanx

Bob

You can change the chain drive for other effective ratios. Here is a company that makes the chain drive gears:http://www.aceomatic.com
